Buddy L Tires and Axles

[studda]

I found a Buddy L hydraulic dump truck from the 50s (I think) that is missing the back tires and axle. The seller only wants $25. The hydraulic bed works very well. It's in good shape except for the lack of rear tires. I was wondering if anybody knew where to get a set (2) of tires and an axle for a Buddy L on the cheap. Here's a picture of what the truck looks like (representational photo) and what the tires look like. I'm reluctant to spend $25 if I can't find the tires and an axle cheap enough to make some profit off of it.
